Question

How do i do this in LINQ – So i dont have to use ForEach or loops?

I can’t seem to figure out how to pass a list when some condition is met and this way loop the collection with LINQ.

products.ForEach(delegate(CustomEcomProducts p)
{                            
  p.VariantProducts = variants.Where(prod => prod.VariantParentID == p.ProductID)
                        .ToList();
});

That’s not what LINQ is for. The Q in LINQ stands for “Query”.

The best/cleanest/most readable way to do this is the following:

foreach(var product in products)
    product.VariantProducts = variants.Where(x => x.VariantParentID == p.ProductID)
                                      .ToList();
